Day out with a 3 year old.

[SN2002]

Hi, I’m going to be taking my niece out in a few days. I’m not sure what we will be doing, but I’m just looking for ideas on what I will need to take with me.
I have the obvious:
Extra clothes (full outfit or just trousers?)
Plasters
Alcohol wipes
Baby wipes
Sun cream
Sun hat
Coat

Am I missing anything? Or will that be okay? This is my first time out with her on my own ever and I want to have everything I need.

T.I.A

Water cup and some snacks!

Yeah, food
Umbrella
Crayons /books

And an infinite amount of patience

Snacks
Packed lunch and own cutlery. If you are planning to eat out, I'd still bring her own cutlery.
Water bottle / cup
Selection of toys
Waterproof coat / trousers
Depending how long or far you are going and if she still needs one - buggy / stroller.
Is she fully toilet trained, if not you'll need a portable potty.
And yes whole outfit, or at least a spare t-shirt, underwear and socks, not just trousers.
A knowledge of where baby changing rooms / toilets are.

Have fun!
